Check Digit Verification of cas no

The CAS Registry Mumber 52884-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,8 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52884-09:
(7*5)+(6*2)+(5*8)+(4*8)+(3*4)+(2*0)+(1*9)=140
140 % 10 = 0
So 52884-09-0 is a valid CAS Registry Number.

Asymmetric propargylation of ketones using allenylboronates catalyzed by chiral biphenols

Barnett, David S.,Schaus, Scott E.

supporting information; experimental part, p. 4020 - 4023 (2011/10/02)

Chiral biphenols catalyze the enantioselective asymmetric propargylation of ketones using allenylboronates. The reaction uses 10 mol % of 3,3′-Br2-BINOL as the catalyst and allenyldioxoborolane as the nucleophile, in the absence of solvent, and

Preparation of syn -Tertiary homoallylic alcohols utilizing allenyltitanocenes generated by reductive titanation of γ- Trimethylsilylpropargylic carbonates

Yatsumonji, Yasutaka,Sugita, Takenori,Tsubouchi, Akira,Takeda, Takeshi

supporting information; experimental part, p. 1968 - 1971 (2010/07/06)

Figure presented syn-Tertiary homoallylic alcohols were obtained by the reaction of α-silylallenyltitanocenes generated by the reductive titanation of γ-silylpropargylic carbonates with Cp2Ti[P(OEt) 3]2 with ketones and fo
